Also, according to experience, the balloon arising inspinning is not to exceed a certain size as otherwise the air resistanceand the centrifugal power of the twisting thread parts would causeundesired tensionsfwhich could be obviated only by reducing the numberoil-evolutions of the spindle. But by such measures the produc tion isdecreased accordingly which is nadmissible. On the other hand theballoon,

while spinning, is to have a size more or less constant in order thatthere may be nearly the same drawing conditions and that the tearingstrength ofthe yarn may remain uniform at the be inning as well as atthe end of the cop. i y

In orderto meet these conditions it has been tried to let the ring framein ring spinning machines, when the thread guide loop is at astandstill,go up and down only as high as the winding strokeand tolower thespindles according to the increasing cop. Other constructions regulatethe cop by means of exclu sive movement of the flyer or spindles. But

In consequence of the large balloon thesemachines are not very suitable for producing large cops, becauseof thevery frequent thread slippings while working. It is also known to adjustthe thread guide loops also upwards in certain reduced proportion to theupwards moved ring frames and rings with stationary spindles. In theinitial stage, when producing large cops, a large balloon is alsoobtained which constantlydecreases towards the end of spinning. But inthis case the equilibrium is distributed throughthe constant decrease ofthe balloon, and the thread guide loops cannot be driven upwardsatpleasure because the angle of the thread-course soon assumes unfavorable dimensions in view of the drawing frame.

ning. Guides 8 are fixed in parts 3 of frame 12. These guides 8 areholding the adjustable thread guide carriers 13 of the thread guide rail14 to which loops 15 are fixed. Spindle rail 9 is provided with holders16 with which rods 17 are adjustably connected. The latter aresupporting head 18 of carrier 13 and with it the thread guide rail14 andthe loops 15. The carriers 13 are also provid'edwithv an adjusting ring4.

When spinning is started the machine is in the position of Fig. 1. Thespindle rail 9 is at the top and, by means of holders 16 and rods 17,holds the thread guide loops 15 with:

rail 14 and its carriers 13 at the height of the drawing frame 19.VVit-h the increase of the cop all these parts are descending until theadjusting ring 4 touches the guide tube 8 above part 3. At this momentthe downward movement of the thread guide loops 15-ceases while spindlerail 9 with spindles 2 sinks further (Fig. 2). During the whole time thethe spindle rail is raised to its initial position, the rod engaging thehead operating to maintain the thread-guide rail in spaced relation tothe spindle rail during the first part of the downward movement of thespindle rail and until the adjustable stop on the head extension engagesthe upper end of the fixed vertical guide.

In testimony whereof I have signed my nameto this specification.

I claim 1. In a cop-winding apparatus, the combination of a verticallymovable spindle rail, with a vertically movable thread-guide raih afixed vertical'guide, ahead slidably mounted'on the upper end of thefixed vertical I guide to engage the under side of the threadguide rail,means limiting the downward movement of the head on'the fixed verticalguide so that the downward movement of the thread-guide rail coincideswith the initial downward movement of the spindle rail, and a verticalrod'attached at its lower end to the spindle rail and with its upper endpositioned to engage the head when the spindle'rail is raised to itsinitial position, the rod engag ing the head operating to maintain thethread-guide rail in spaced relation to the spindle rail during thefirst part of the downward movement of the spindle railand within thelimits of the downward movement of the head on the fixed vertical guide.
